I would be interested, however cannot spend time right now to work on that subject. > I am wondering if someone have already tryed this PQ3 feature ? > I guess this would require some kind of hook in the kernel ... Just some random bits I found in the web: http://developer.apple.com/documentation/Hardware/DeviceManagers/pci_srvcs/pci_cards_drivers/PCI_BOOK.250.html The Interesting part is: "Thus, the address swizzle is completely transparent to software." So, I would just try to setup some memory mapping and turn on little endian mode to access that area... MMMV. Just a guess.
